INNERSOLE CHANNEL FILLER.

`lipplcatrm filed April 2G, 1924. Serial No. 709,171.

rilhiainvention relates to .leather channel. filler strips tor shoe bottoms., said strips being .shaped in cross section to lill the channel oit a welt innersole lett open by lifting the channel flap kand then trimming it at the inseam trimming operation. A shoe having a bottoni including` a channel liller strip ot this character is disclosed and tivelythin, cheap material which may be oi short lengths.

The channels to be lilled are ot substantially triangular cross section and it is desirable that the liller strip be out quite ac.- eurately, leaving clean, sharp edges. lt is there'lore desirable that all the edges of the strip be formed from the grain side portion et the leather since this is relatively close grained and uniform while the flesh side, particularly in the heavier grades ot leather, is stringy and porous and often hard and relatively inflexible. lt is evident that it a single thickness ot leather ot the desired width be out diagonally to form two strips each of triangular cross section, two ot the edges of one andl one ot the edges of the other, are formedirom the flesh side of the material. By fixing together with their vflesh sides toward each other a. pair of relatively thin strips opt leather to produce the desired thickness of strip, and cutting the compound strip diagonally, two channel tll .5er strips each of triangular cross section are produced, all the edges of both ot which being formed trom the grain side portion o'l'I the leather. This is the method ot building the ller strip contemplated by the present invention.

For a more complete understanding there of reference may be had to the accompanying drawings in which Figures l and 2 are plan and edge views of a .leather strip.`

an edge View showing the blanlr built up from short lengths of strip material. i

Figure e' is a plan of the saine.

Figure 5 shows in plan the strip rut to narrower Widths.

Figure 6 shows each of these widths again divided to form blanl-rs rectangular in `cross section. l

Figure 7 is a perspective showing the blank cut on a diagonal to torni liller strips ot the desired triangular cross section.

Figure ,8 isa similar view but showing the lan'iinations partly separated in order to disclose the surfaces of the individual ele- .ments or laminations from which the liller strip formed. Y

Figure 9 shows in perspective a piece of linished channel filler strip material.

Figure l0 shows in perspective a continu ous length oi' such liller strip material wound on a reel.

Figure 11 represents a cross section of the forward portion ot a welt shoe along the line ll-ll ot Figure'lQ and showing the .filler strip in position.

Figure l2 illustrates a bottom plan of a lasted shoe bet-ore the outer sole has been fixed in position and showing the filler strip in position.

Th procedure in 'building up the iller strips according to this invention is as follows. Relatively thin strips ot leather .l are prepared as in Figures l and 2, the strips, if desired. being cut from short lengths or scrap material. These strips are cemented together with their flesh sides toward each other, the joints 2 between the strips of each ply 3 beingl staggered so that a continuous length is produced as shown in Figures 3 and a. lVhen this length is of suliicient width itis then cut longitudinally as shown in Figures 5 and 6 the proper number of times to produce blanks of the desired rectangular cross sections as shown at 6 in Figure 7, each of a width equal to the width of the channel to be filled. lt is preferable to cement the individual pieces together in relatively wide widths in order to avoid excessive handling and in order to facilitate the cementing oi? the parts together. Ot cours desired, however, the strips "ght be cui, directly to the desired widths, j iar-fv ticularly Where it is desired to use material which is oit insufficient Width to form the Wider strips therefrom. The strips 6, as shown in Figure 7. are then cut diagonally along the line 7 each to form two continuous channel filler strips of triangular cross section as shown at 8 in Figure 9.

It will be noted'from an inspection of Figures 8 and 9 that each filler "strip is formed of laminations 9 andflO. one of which is but one-half the width ofthe other, the dividing surfaces between the laminations as at 1l and l2. in the Ipreferred form, being parallel to one tace of the strip and presenting the flesh sides of the leather of which the individual laminations are composed` Since these flesh sides are cemented together, the edges of the strip Which are exposed as at l5, 16, and 17 are all from the grain side of the material so that they may be cut clean and sharp.

The flesh sides being cemented together before the blank is eut diagonally are held in proper relationship and are not permitted to fray out and leaverough edges, The eX- posed edges ot the finished `filler strip are ot material which is suliiciently flexible to per`- mit the strip to be laid in the channel about the innersole as shown at 20 in Figure l2. thus completely lling channel and producing a substantially smooth surface Within the stitching rib 2l acrossthe entire Width of the innersole face as is shown more clearly in Figure 11. In this ligure the innersole is shown at 25, the outer sole at 26, the lining and upper at. 27 and the Welt at 28,.

The finished filler strip material may be wound on reels as shown at 30 in Figure l0 and be laid in the innersole channels and cut olf as desired trom the continuous piece.

Having thus described this invention it should be evident that various changes and modilieations might be made therein Wilhout departing from its spirit or scope as de fined by the appended claims.

T'elaim:

l.A A laminated leather strip of triangular cross section'formed from grain leather and each edge ofwhich presents the grain 'tace of the leather.

2. An innersole channel filler strip of triangular cross section comprising a pair ot strips of grain leather, one of which is but onelhalf the Width ot the other. secured together with their flesh sides in contact.

3. An innersole channel filler strip ot triangular cross section comprising a pair oit strips of grain leather secured together with their flesh sides in contact, the line ol" contact ot' said strips being substantially par-- allel to one tace of the filler strip.

4. The method of making an innersole channel filler strip Which comprises securing together layers of grain leather to form a continuous length of two ply material, the flesh sides of the plies being in contact. and cutting the length along` a diagonal to form a pair of filler strips each of triangular cross section each edge ot' which is from the grain side portion ot the leather.

In testimony whereof I have affixed my signature.
